Riemann Integral

High Quality Content by WIKIPEDIA articles! In the branch of mathematics known as real analysis, the Riemann integral, created by Bernhard Riemann, was the first rigorous definition of the integral of a function on an interval. The Riemann integral is unsuitable for many theoretical purposes. For a great many functions and practical applications, the Riemann integral can also be readily evaluated by using the fundamental theorem of calculus or (approximately) by numerical integration.
